[QUOTE="me2, post: 364188, member: 3825"] CNC Plasma Cutter Stuff My apologies to people subscribed that don't want to read about this. I am going to be very brief on this topic. As I said previously, I'm building a cantilever design, loosely based on this. [img]http://farm6.staticflickr.com/5102/5690844878_d44901516f_o.jpg[/img] I'm doing this for a few reasons. 1) Be able to cut from/onoversized sheets and not have to slice them down to size the way I would on a typical gantry design. 2) I'm probably going to make the Y axis arm flip up out of the way when its in storage, so it doesn't take up as much room. 3) I'm probably going to make the table separate from the cutter, for flexibility. I suspect that the CNC cutter part will weigh less than 75 pounds. In some cases I might be taking the cutter to the material (steel) rather than putting the material under the cutter. If it doesn't work out, I'll change it to be a gantry design, using the same parts. I decided to buy all the guides for my cutter rather than make them. The X axis is going to have the most stress on it, because of the overhanging nature and thus I bought the heaviest guids for it. I bought these for $150. [ATTACH=full]89084[/ATTACH] They are 48 inches long. The saddle that travels on the X axis is going to be about 12" wide, so that will leave about 36 inches of X axis travel. The Y axis arm is going to be a piece of 2x3 aluminum that I already have. I'm using aluminum because I want it to be light to lessen the overhang burden on the X axis saddle and rails. I bought these for $175. [ATTACH=full]89085[/ATTACH] They are 37 inches long. The saddle on this axis will be about 6 inches and thus I'll have 30+ inches of travel. I want over 30 inches becuase some sheet steel is sold in 5x10' sheets and half of 5' is 30 inches. I am going with a moveable torch head off the bat, for better piecing and because I'll probably put a small router on it someday. I bought this for $125. [ATTACH=full]89086[/ATTACH] 90mm of travel, set up to accept a NEMA 23 stepper motor. Plug and play. I'll document the rest of the components as I buy them and explain things as I put it together.
